I know about humans, and how we have adapted to different eviornments with skin and hair color, but I want something a little bit different for my creatures. They are amphibious humanoids, and live...
I have two planets that are the exact same size and mass of Earth. They orbit each other, and have an orbital period of one day. How far apart are they? The planets both orbit a star the same as t...
I have two earth clones, in essence, separated by *16550 miles (26350 kilometers). They are, of course, tidally locked, and orbit each other once every 24 hours. These planets orbit a sun identical...

Before we begin, this system is created by aliens, and all orbits are on the same plane. These orbits are similar to earth's in shape. So, none of this has to occur naturally it just has to be stab...
Without tidal locking, would it be possible to have a planet with a region roughly the shape and size of the USA and Canada in which it is always "day"? (By day I mean at least as bright as a clear...
In my story, I have a fairly advanced human race who is at the point they want to start terraforming planets. Of course, all of the materials necessary have to come from somewhere, and the proposed...
Alternate question title: From Fungi to a Fun Guy So, I asked a previous question about which non-animal would be the likeliest to evolve sentience. The answer turned out to be fungus, since mycel...
For my fantasy world, I have what I think is a really cool idea. The world is flat, and elliptical in shape. If you touch the silvery edge, well, let's just say bad things will happen. (Not relevan...
For a story I am writing, I need a planet covered in a shallow ocean. What I mean is that I want the majority of the planet's surface (=> 60%) to be in the photic zone of the ocean. This planet...
Forget about how we get it there, some kind of top secret experiment on mars gone wrong in all the right ways. If somehow Mars's core was mixed with some amount of antimatter, and assuming 100% of...
So, I have an aquatic humanoid species that I want to be able to use echolocation. They are extremely similar to humans,with some minor differences, like gills. (The reason I include this tidbit is...
I drew a little map of a continent, but there is one area that I'm not sure about; the climate. As for the location of this map, remove North America and replace it with this map. The northernmost ...
For my current purposes, assume we have two planets identical to earth. So, could two of these planets form a stable binary system, and still be close enough to see the green foliage on the surface...
When the earth is flung out of the solar system as per Josh Pirhi's question, not everyone embarks on a spaceship. Instead, as earth becomes a rogue planet, a group of survivors created a self sust...
Would it be possible to have a planet made up of about 60-70% water with no landmasses larger than Australia? I would like this planet to be as earth like as possible, but I'm open to changing aspe...
I have decided on my preferred method of zombie apocalypse. I have chosen super leeches. But I have run into some problems, I'm not entirely sure if such a thing would be possible. I have a few ide...
I have an alien species that is my pet project. Now I'm to reproduction, which I have a specific idea for, I'm just not sure exactly how it works. My creatures are aquatic, and everything goes on u...
Traditionally, a Cyclops has one eye, as well as some other aliens in fiction. My question is simple: Would there be any situations, Earth-like or otherwise, where a creature would benefit from h...
I'm going on vacation, and browsing through my texts on the latest iPhone. Uh oh, my private airplane, which for some stupid reason has no tracking devices, crashes onto some undiscovered island. E...
I've heard a lot of people say that having two tidally locked planets close together would have adverse affects on both planets. I have two tidally locked planets at a distance of 16,550 miles apar...
Now, bear with me because I know very little of mycology. I just know that mushrooms taste good, and that fungi is very complex with lots of different uses. For my fantasy story, I want a societ...
You have a planet about the size of Earth. It needs to be continually dark, with just the slightest bit of light. Or no light at all. It makes little difference to the aliens that live there. But, ...
I was thinking, and I came up with an alien race, which enthralled me. I was just wondering if these creatures would plausibly evolve this way. (Info dump time These aliens are humanoid. While t...
What is the minimum size of a planet that could harbor human life? You get to decide what the atmosphere is, but I'm reasonably sure that O2, CO2, and H2O are necessary components of the atmosphere...
